Background: Vietnam harbours a high species richness of venomous snakes with >60 recognised species but snakebite pathology and treatment are still understudied, particularly in northern Vietnam.
Methods: A retrospective study from 2008 to 2020 was conducted, focusing on snakebite cases at the Poison Control Center of Bach Mai Hospital, a major centre in northern Vietnam for treating envenoming incidents.
Results: A total of 5805 snakebite cases were reported over 12 y. The demography of patients was predominantly male snakebite victims (70%), middle-aged (30-59 y) and mostly from rural districts. Cobra (Naja spp.) attacks were the main culprit, accounting for 39% of cases, and most snakebites occurred in the rainy season. The majority of patients were from Hanoi, but the percentage of cases from other provinces increased over the years up to 75% in 2020. The highest number of snakebites were recorded from communes with snake farms.
Conclusions: Male gender, rainy season, rural residency and snake farming were identified as major risk factors for contracting snakebites. Multicentre hospital studies, cross-sectional community surveys and a central snakebite database are needed to better understand and deal with snakebites in Vietnam.

Background: Snakebite envenoming is a medical emergency that requires rapid access to essential medicines and well-trained personnel. In resource-poor countries, mapping snakebite incidence can help policymakers to make evidence-based decisions for resource prioritisation. This study aimed to characterise the spatial variation in snakebite risk, and in particular to identify areas of relatively high and low risk, in Eastern Province, Rwanda.

Snakebite envenomation is a neglected tropical disease that affects millions of people in sub-Saharan Africa, including Sudan. The severity of snakebite envenomation ranges from mild to severe, and can even lead to death. Sudan has a high burden of snakebite envenomation, with an estimated 12 632 cases and a mortality rate of 2.

Background: Snakebite envenoming is a critical medical emergency and significant global public health issue, with India experiencing the highest annual snakebite deaths. Sea snakes in the Indian Ocean pose a severe threat to rural fishermen due to their potent neurotoxins.
Methods: From December 2020 to December 2021, we conducted surveys at 15 fishing ports in East Medinipur, West Bengal, and Balasore, Odisha, India (between 21.
